INCANDESCENT BURNER.

SPECIFICATION forming part of Letters Patent No. 791,894, dated June 6, 1905.

Application filed February 18,1905 Serial No. 246,246.

To all whom it may concern.-

Be it known that I, DAVID FRIED, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Incandescent Burner, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide an incandescent or mantle burner which will be of simple, durable, and economic construction and which can be attached to a bracket and be supported in a pendent, upright, or a horizontal position or intermediate positions without in the least interfering with the position of the mantle relative to its supporting-tube.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is a side elevation of the improved burner, and Fig. 2 is a sectional view of a portion of the body of the burner and a side elevation of the regulator removed from the body.

The body A of the burner consists of a base 10 of any approved form, an outer tube 11, integral with the base, and a gas-supply pipe 12, which leads to the mantle 13 and its holder 14:. The supply-pipe 12 is open at the base of the body, and is enlarged at that point, and is likewise provided with an interior thread 12 just above its expanded portion. The mantle 13 is secured directly to the holder let in any approved manneras, for example, the mantle is wired, clamped, or cemented to its holder-and the said mantle is closed at the top except when the burner is used in an upright position. In placing the mantle and its holder upon the body of the burner the attachment is made direct, and bar-supports or their equivalents are not used, but instead the holder 14 is provided with a bayonet-slot 15, and the outer body-tube 11 has a pin 16 fixedly attached, which pin when it has entered the horizontal portion of the slot 15 locks the mantle-holder to the body of the burner.

The regulator B is removably secured directly to the supply-tube 12 of the burner, and consists of a body 17, having a threaded opening 18 at its inner end to receive the threaded end 19 of a house-pipe 20, and within the said body a partition 21 is located, dividing the body. into two chambers 22 and 23, and said partition has openings 2 T therein, controlled by a suitable slide 25, also provided with openings. In the sides of the chamber 23 slots 26 are made for the admission of air supplied thereto through openings 28 in the bottom of a shell 27, encircling the slotted portion of the body 17. The upper end of the body 17 of the said regulator is open and is provided with an exterior thread 29, which upon the assembling of the parts of the burner is screwed into the threaded portion 12 of the supply-tube 12. It will thus be observed that the regulator and body of the burner are so intimately connected that one cannot he accidentally separated from the other, en*

abling the burner to be screwed to the fixture and support the mantle in an inclined, horizontal, or upright position, producing the proper flame in either of said positions.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with an incandescent burner having a single pin projection extending from one of its sides, and the regulator for the burner, which regulator is provided with means for direct attachment to a source of gas-supply, of a mantle-holder having a sharply-defined L-shaped slot therein to receive said projection, and a mantle secured at its base directly to the holder and having no other support, whereby the burner may be placed in various positions relative to a given surface, as specified.

2. As an improved article of manufacture, an incandescent burner having its tubular body portion provided with a projection at its forward end, a mantle-holder fitted to the said body and provided with an L-shaped slot to receive the projections from the said body, a

IO later having an interior thread at its base,

whereby the burner in its entirety can be applied directly to a fixture and will successfully operate in any desired position.

In testimony whereof I have signed my name to this specification in the presence of two sub- I 5 scribing witnesses.
